Even Better Bering : Slew Resistant, Print in Place
thingiverse
This is a bering I designed. The center hub is will fit an 8mm hex wrench, or any 8mm hex axel. Bering designed to print in place and provide resistance to slew superior to ball bearings or "barrell" berings. Also each individual bering has a small through slot to assist in breaking free if needed. NOTE: This bering actually performs better if/when a bering or 2 breaks and falls out. 3 berings can fail and the hub will still be held in place (and maintain suprisingly little slew), loose 4 bearings and very soon they will all bunch up and there will be enough space for the hub to come free. This can be mitigated by increasing the diameter of the inner shaft of each bering, which also means re-building the outer race (at least) NOTE this bearing is designed with .2 mm gaps between berings and races. This tolerances is to allow for "sloppy" printers or materials with significant expansion/shrink and variation issues. This bering has been successfully printed several times with PTEG on a creality ender3 at 0.15 layer height with PTEG I was getting axial slew no more than 0.5 degrees, and surprisingly resistant to slew. Props go out to Gear Down For What #geardownforwhat makers muse and AVE for the inspiration. I am including the bering as one RTP unit, and the hub, individual bering, outer race as individual files.
